IOS28 is the first IOS to be split into multiple modules, each its own ELF ARM binary, rather than all of IOS being part of a single monolithic binary. Its ES module includes ioctls that retrieve shared contents.
The only game that uses it is Metroid Prime 3: Corruption, and this IOS was included in the update partition of the disc.
